Use of Preoperative Transthoracic Echocardiography to Predict the Prognosis after Off-Pump Coronary Artery Bypass Grafting / 대한마취과학회지

ABSTRACT

BACKGORUND Echocardiography is usually performed for preoperative cardiac evaluation before coronary bypass graft surgery. if the variables detected by this noninvasive method could predict the outcome of the off-pump coronary bypass surgery (OPCAB), it would be very helpful. The purpose of this study is the evaluation of preoperative transthoracic echocardiographic findings as the predictor of OPCAB outcome. METHODS: We evaluated the relationships between preoperative variables identified by the transthoracic echocardiography and postoperative outcomes. RESULTS: Among the doppler findings trans-mitral flow shows no relationship with the postoperative outcome. But, left ventricular mass had the predictability of postoperative time of extubation, iCU stay, and hospital stay. CONCLUSiONS: Left ventricular mass can be used to predict the outcome after OPCAB and There are the need of further study to find out the reason the left ventricular mass show relationship with the postoperative outcome.
